Canister Vent Solenoid

Typical Canister Vent (CV) Solenoid

During the Enhanced EVAP System test monitor, the Canister Vent (CV) solenoid (Figure 99) seals the EVAP canister from atmospheric pressure. This allows the EVAP canister purge valve to obtain the target vacuum in the fuel tank during the monitor run.
